“…Also, complex structure coplanar waveguide (CPW)-fed metamaterial-inspired antennas were presented using Composite Right/Left Handed (CRLH) metamaterial for Bluetooth and WLAN/Wi-Fi applications [12,13], whereas a modified split-ring resonator-based short-ended metamaterial antenna was discussed, which covered only Wi-Max applications [14]. A coplanar waveguide-fed planar antenna was proposed only to cover IEEE 802.11ac applications with reduced radiation hazards [15,16]. So, the widespread use of the newest technologies, like Wi-Fi 6 and many others, makes it easiest to understand how the utility of technology improves among the general public as it develops.…”

A CPW-fed hexagon-shaped split ring resonator (H-SRR) antenna consisting of three concentric SRR rings is proposed for triband WLAN/WiMAX and Wi-Fi6 applications. A single port optimized antenna has a size of 43 × 22 × 1.6 mm 3 with two ports, and a multiple-in-multiple-out (MIMO) antenna based on the same H-SRR design is of size 95 × 52 × 1.6 mm 3 . The use of metallic loadings between the rings led to an impedance bandwidth of 21%/65% for the single-port H-SRR antenna and 33%/66.5% for the dual-port H-SRR antenna in the 2.4 GHz band and 5.2/6 GHz bands. The antennas exhibit a gain in the range of 2-2.7 dB and good radiation characteristics. Also, the proposed antenna design achieves the isolation of more than 30 dB without using any de-coupling network making the structure simple and compact. For tri-band applications of the proposed dual port antenna, the MIMO parameters ECC, TARC, DG, and MEG are found about < 0.005, < −10 dB, ≤ 10 dB, and < −6 dB, respectively in the 2.4/5.2/6 GHz bands without any decoupling structure. Measurements with a commercial transmitter at 5.8 GHz confirmed that these antennas offer better Wi-Fi 6 connectivity. Thus, the results confirm that the novel features of the proposed antennas are simple structure, wideband operation, and moderate gain with a compact size in the 2.4/5.2/6 GHz bands, and therefore, these presented antennas are useful in the current WLAN/WiMAX systems as well as upcoming Wi-Fi 6 applications like routers.

“…The absence of Transverse Magnetic (TM) modes in the SIW makes it very useful in the filter design. Even though planar transmission lines such as coplanar waveguide fed microwave components were developed [2][3][4][5], the high degree of miniaturization was not attained. However, SIW has the advantage of compact size, low cost, light weight, and is of planar in nature.…”

In this paper, a Substrate Integrated Waveguide (SIW) band pass filter loaded with a square Complementary Split Ring Resonator (CSRR) etched with Defected Ground Structure (DGS) is proposed. SIW is a promising candidate for the design and development of various microwave and millimeter wave components useful in communication systems. Due to the evanescent mode propagation and TE 10 mode of the cavity, dual band (5.57/7.84 GHz) filtering is achieved with a 3 dB fractional bandwidth (FBW) of 6.8% and 4.1%, respectively. The dual bands achieve a low insertion loss of 1.8 dB and 2 dB, respectively. Cursor head DGS improves the out of band rejection to a greater level. The configuration is investigated with its corresponding circuit and simulated using Computer Simulation Technology (CST) software. The prototype is fabricated using a Rogers substrate with ε r of 3.5 and tested. This prototype finds its application in C band satellite communication systems. The measured results are consistent with the simulated ones.

In this article, a novel Hexagonal Split-Ring Resonator enclosed Circular Split-Ring Resonator (HSRR-CSRR) inspired printed antenna is presented for sub-6 GHz 5G NR and IEEE 802.11ba/be applications. The proposed antenna comprises an HSRR-CSRR and a D-SHSRR metamaterial unit cell with a partial ground plane. The designed antenna is printed on a low-cost FR-4 substrate with dielectric constant ε r of 4.4, thickness of 1.6 mm, and loss tangent of 0.02. An HSRR-CSRR metamaterial structure is designed to get the three distinct resonance frequencies at 3.5 GHz, 5.05 GHz, and 6.2 GHz, respectively. To cover the entire band of Sub-6 GHz 5G NR (5-6 GHz), a Double-slit Single Hexagonal Split Ring Resonator (D-SHSRR) is designed for 5.8 GHz and loaded along with the HSRR-CSRR. The operating principle, equivalent circuit, and parametric extraction of the HSRR-CSRR structure are examined. Compared to the conventional antenna, the proposed antenna has a compact size of 0.38λ g × 0.52λ g × 0.03λ g . The antenna parameters have been investigated using Ansys HFSS 15.0 software. The measured and simulated results are in good agreement.
